DAPS: An Expert System for Damage Assessment of Protective Structures
An automated reasoning code for the damage assessment of protective structures (DAPS) is being developed within the Air Force. Protective structures in this context will be synonymous...
KBES and Interactive Graphics
Knowledge Based Expert System (KBES) is at research and testing stage at present. Engineers have begun to accept Interactive graphics System (IGS) as a tool in decision making. This paper...
Applications of Automated Interpretation to Sensor Data
This paper focuses on potential applications of the AISD. (A knowledge-based concept for automating the interpretation of sensor data) concept in civil engineering. A number of potential...
Base Isolation in the Design and Construction of Power Plant Structures
This technical paper summarizes the results of some of the recent studies performed to assure technical feasibility in isolating safety-related nuclear power plant structures. The particular...
Clean-up in the Rockies
The shallow aquifer flowing beneath the Rocky Mountain Arsenal, just outside of Denver, has become contaminated with a number of toxic substances. Until the arsenal can be cleaned-up,...
Dynamics of Fender and Rack Systems for Docking Ferries
A dynamic analysis of a ferry fender and rack system is developed based on the conservation of energy principle and Newton's laws of motion. The dynamics of the interaction...
Floating Bridges in Short-Crested Random Seas
Four large concrete floating bridges located in Washington State have been the subject of extensive analytical modeling for dynamic response to storm waves. The dynamic analysis of the...
Regional Risk Assessment of Existing Buildings
This paper describes current research underway at Stanford University designed to develop a methodology for determining high risk buildings in a region. The work involves developing a...
Evaluation of Seismic Strengthening of an Existing Building Using Base Isolation
This paper summarizes a study performed by Englekirk and Hart, Inc. to evaluate the feasibility of using base isolation to seismically upgrade an existing highrise building. To realize...
Dynamics of 3-D Base Isolated Structures
The work described in this paper concerns the dynamic behavior of asymmetric base isolation systems consisting of laminated rubber bearings and hysteretic dampers. It is shown in this...
The Earthquake Barrier
The earthquake barrier protects buildings from the horizontal ground vibrations of an earthquake by installing a 'force barrier and an energy barrier' at the...
Diffraction Forces on Axisymmetric Bodies
Use of a Green function satisfying the governing differential equation and all boundary conditions except those on the boundary of the structure yields an integral equation, when these...
Seismic Isolation of Bridge Structures
Seismic isolation concept has been extensively developed and applied in New Zealand and is receiving increased attention in the United States. Two bridge projects have incorporated the...
Disney Engineers Voyage to the Deep
The main show at the Living Seas Pavilion, part of Walt Disney Production's EPCOT Center, Lake Buena Vista, Fla., is a visit to a tropical coral reef deep under the ocean....
Design of Wharf Facilities, Guam, M.I., to Accommodate Difficult Site Conditions
A wharf facility currently under construction in Guam, Mariana Islands, for the U. S. Navy utilizes precast concrete box caisson construction to satisfy difficult site conditions. To reduce...
The Application of Computer Simulation in the Design of Marine Terminals and the Scheduling of Ship Traffic
